An Asian immigrant has claimed an Auckland bus driver has discriminated against her and repeatedly refused to let her on board.

Bomi Kim, who is pregnant and has two young children, said she was trying to board the bus last week to take her son to the hospital but the driver refused to open the doors, according to the NZ Herald.

Ms Kim filmed herself knocking on the doors as the driver appeared to ignore her. Her son can be seen peering through the glass doors.
